Protein Family Models

This family consists of bacterial antibiotic resistance proteins, which confer resistance to various aminoglycosides they include: aminoglycoside 3'-phosphotransferase or kanamycin kinase / neomycin-kanamycin phosphotransferase and streptomycin 3''-kinase or streptomycin 3''-phosphotransferase. The aminoglycoside phosphotransferases inactivate aminoglycoside antibiotics via phosphorylation [2]. This family also includes homoserine kinase. This family is related to fructosamine kinase Pfam:PF03881. [1]. 2163618. Cloning of aminoglycoside phosphotransferase (APH) gene from antibiotic- producing strain of Bacillus circulans into a high-expression vector, pKK223-3. Purification, properties and location of the enzyme [published erratum appears in Biochem J 1991 Feb 1. Sarwar M, Akhtar M;. Biochem J 1990;268:671-677. [2]. 2167474.

aminoglycoside phosphotransferase family protein catalyzes the phosphorylation of small molecule substrates such as aminoglycoside antibiotics and N-acetylhexosamine; similar to Neisseria meningitidis N-acetylmuramate/N-acetylglucosamine kinase
